실험 절차

(S)-3-(4′-Cyano-biphenyl-4-yl)-2-{[(3R,7S)-3-(4-hydroxy-phenyl)-1-methyl-2-oxo-6-((S)-1-phenyl-propyl)-2,3,5,6,7,8-hexahydro-1H-4-oxa-1,6-diaza-anthracene-7-carbonyl]-amino}-propionic acid methyl ester (15 mg) was dissolved in 1 mL of DMF and 3,4-dichlorobenzyl bromide (46 mg) and potassium carbonate (26 mg) were added. The mixture was stirred at room temperature for 6 hours and was poured onto ethyl acetate and saturated sodium bicarbonate. The organic layer was dried over sodium sulfate and concentrated. The residue was purified over silica (hexanes-ethyl acetate-MeOH, 6-4-0.1) to provide (S)-3-(4′-cyano-biphenyl-4-yl)-2-{[(3R,7S)-3-[4-(3,4-dichloro-benzyloxy)-phenyl]-1-methyl-2-oxo-6-((S)-1-phenyl-propyl)-2,3,5,6,7,8-hexahydro-1H-4-oxa-1,6-diaza-anthracene-7-carbonyl]-amino}-propionic acid methyl ester (18 mg, LC/MS: m/z 894). 1H NMR (400 MHz, ,d6 acetone): 7.92-7.81 (m, 5H), 7.66 (s, 1H), 7.57 (m, 3H), 7.43 (m, 1H), 7.32-7.21 (m, 7H), 7.01-6.94 (m, 5H), 6.66 (s, 1H), 5.60 (s, 1H), 5.1 (s, 2H), 4.78 (m, 1H), 3.74 (s, 3H), 3.66 (m, 1H), 3.56 (d, 1H), 3.46 (m, 1H), 3.35 (s, 3H), 3.34 (d, 1H), 3.02-2.98 (m, 2H), 2.27 (m, 2H), 1.90-1.66 (m, 2H), 0.60 (t, 3H).
